The trait for 'black feet in ferrets' is a recessive trait encoded by "f". White feet are encoded by a dominant allele "F".

An ecological study in ferret country conducted by Mrs. Wright found that out of 1000 ferrets:

- 360 had black feet
- 480 had white feet and were heterozygous
- 160 had white feet and were homozygous

Using this information, find the allele frequencies for F and f.

Remember, "F" = p and "f" = q

A. F = 0.4 and f = 0.6
B. F = 0.7 and f = 1
C. F = 1 and f = 0.7
D. F = 0.7 and f = 0.3

Answer :

For the trait for 'black feet in ferrets' is a recessive trait encoded for by "f". white feet is encoded for by a dominant allele encoded for by the letter "f" the sum of the frequencies for f and f all alleles must equal 1.

Let's calculate the frequency of the f allele (p):

The 360 ferrets with black feet are homozygous recessive (ff), so the frequency of the f allele is sqrt(360/1000) = 0.6

The 480 heterozygous ferrets (Ff) have one f allele each, so the frequency of the f allele is 480/1000 x 0.5 = 0.24

The 160 homozygous dominant ferrets (FF) have no f alleles, so the frequency of the f allele is 0.

The sum of the frequencies of f and F is 1, so the frequency of the F allele (q) is:

q = 1 - p = 1 - 0.6 = 0.4

Therefore, the answer is (a) f = 0.4 and f = 0.6.
